    • A magnetic tape apparatus loading and threading mechanism that moves a cartridge tray accommodating a cartridge between an eject position where the cartridge is mountable in the tray and a mount position where the cartridge reel is engaged with the apparatus. The cartridge tray is engaged with a loader drive plate having a loader drive roller in a loader drive cam groove formed in a loader drive gear. A threading mechanism moves a leader block, engageable with a leader pin at the tip portion of a magnetic tape in the cartridge, between an unload position near the cartridge tray at the mount position, and a load position in the reel of the magnetic tape apparatus. The leader block is engaged with an arm member having a threader drive roller in a threader drive cam groove formed in a threader drive gear engaged with the loader drive gear. At the unload position, the leader block is at a retracted position where the leader block is retracted from the cartridge in the mount position, or a leader pin captured position where the leader block is engaged with the leader pin at the tip portion of the magnetic tape in the cartridge. A single source drives the loading and threading mechanisms, so as the loader drive gear is rotated, the cartridge tray is moved between the eject and mount positions, and the leader block is rotated between the retracted and leader pin captured positions, and moved between the unload and load positions.

    • An object of the present invention is to provide a wavelength selectable laser oscillator in wavelength tunable laser by which high-speed tuning of wavelength can be achieved while utilizing continuous-wave laser beam as the excited laser beam. The wavelength selectable laser oscillator in wavelength tunable laser comprises a laser resonator composed of opposed mirrors each having a prescribed reflectivity on the outgoing side and a total reflection mirror which does not transmit light, but reflects the light; a wavelength tunable laser medium disposed in the laser resonator and capable of laser oscillation in a wavelength zone of a prescribed range; an acousto-optical crystal disposed in the laser oscillator and to which is inputted the outgoing light from the wavelength tunable laser medium; an acoustic wave inputting means mounted on the acousto-optical crystal and for inputting an acoustic wave to the acousto-optical crystal; and a continuous-wave laser for inputting excited laser beam into the laser resonator; the laser beam outputted from the mirrors on the outgoing side being utilized as the outgoing laser beam from the laser resonator.
